NORMAN — After a Cleveland County jury found Alton Nolen guilty of first-degree murder for the 2014 beheading death of Colleen Hufford last week, he will at least serve life in prison. Whether he will he be sentenced to death remains up in the air.

On Monday, the 12-person jury made up of eight men and four women took less than two hours to come back with a sentencing recommendation for five assault with weapon charges Nolen, 33, faces in connection with the Sept. 25, 2014, attack at Vaughan Foods.

The recommendations for Nolen ranged from 55 years to life in prison.

The jury's sentence recommendation for the first-degree murder charge is still undetermined and probably won't be decided until the end of the week.

Following the announcement by the jury, the court didn't waste any time starting the process for the remaining capital crime.

One witness testified Monday, but it was clear what the defense's argument for this stage would be — to show the jury Nolen is intellectually disabled and, therefore, under Oklahoma law — disqualified from receiving the death penalty.

Because the jury rejected Nolen's insanity defense and found him guilty on all counts, the burden shifts to the defense to persuade the jury Nolen is intellectually disabled.

To help prove the defense's argument, his attorneys called psychologist Jeanne Russell to testify, one of two psychologists the defense called in the first stage of the trial to aid in Nolen's insanity defense.

Russell said she conducted an IQ test, which revealed Nolen had an IQ of 69 — a score that met the subaverage general intellectual functioning requirement in determining whether Nolen is intellectually disabled.

However, state law requires Nolen also would have to display limitations in adaptive functioning, and the onset of his disability would have to be manifested before the age of 18, to qualify as intellectually disabled.

Russell said Nolen met all of the requirements.

If the jury decides Nolen is intellectually disabled, the most stringent punishment he could receive is life in prison without the possibility of parole.
